Expert Tips

Have fun making other colors and flavors of cupcakes by using lemon, lime, strawberry, raspberry or watermelon gelatin.

Try paste food color! It can be purchased at cake decorating and craft stores. The color is more concentrated, so a little goes a long way.

An easy way to frost cupcakes is to carefully dip tops into the frosting, give a slight twist and remove. Finish off with a swirl of a knife if needed.
